The WARN_ON() backtrace is unrelated to USB - it is due to SCSI calling vmalloc/vfree with interrupts disabled. People are working on that.
As for this:
May 14 23:57:09 chimera kernel: usb usb2: string descriptor 0 read error: -108 May 14 23:57:09 chimera last message repeated 2 times
It has been reported before and I assume people are working it, but it would be nice to have confirmation of that... - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
